Background and Aim: The aim of this study was to investigate the shear bond strengthof composite to Emax porcelain using different methods of ceramic surface preparation (in vitro). Material and Methods: In this laboratory study, 36 porcelain disks were made and divided into four equal groups. The first group was prepared by sandblasting with 50 micron alumina particles, in the second group rec...
The Kaposi's sarcoma-associated herpesvirus (KSHV) K1 gene encodes a polypeptide bearing an immunoreceptor tyrosine-based activation motif (ITAM) that is constitutively active for ITAM-based signal transduction. Although ectopic overexpression of K1 in cultured fibroblasts can lead to growth transformation, in vivo this gene is primarily expressed in lymphoid cells undergoing lytic infection. H...
In a recent work, the combinatorial interpretation of the polynomial α(n; k1, k2, . . . , kn) counting the number of Monotone Triangles with bottom row k1 < k2 < · · · < kn was extended to weakly decreasing sequences k1 ≥ k2 ≥ · · · ≥ kn. In this case the evaluation of the polynomial is equal to a signed enumeration of objects called Decreasing Monotone Triangles. In this paper we define Genera...
Acyl-coenzyme A:cholesterol acyltransferase (ACAT) catalyzes the esterification of cholesterol with long chain fatty acids and is believed to play an important part in the development of atherosclerotic lesions. To facilitate the study of ACAT's role in this process, we have used the human ACAT K1 clone previously described (Chang, C. C. Y., Huh, H. Y., Cadigan, K. M. and Chang, T. Y. (1993) J....
This paper presents a solution to increase the throughput of an HF (High Frequency) physical (PHY) layer in particular to allow for services such as IP over HF. Additionally, this new PHY layer can improve the adaptability of the waveform to the channel variations, in particular to limit the retransmissions due to errors. Taking into consideration the existing HF spectrum occupancy and its high...
Let S(R) be an o-minimal structure over R, T ⊂ R k1+k2+l a closed definable set, and π1 : R k1+k2+l → R12 , π2 : R k1+k2+l → R, π3 : R k1+k2 → R2 the projection maps as depicted below.
We introduce a new invariant for C?-algebras of stable rank one that merges the Cuntz semigroup information together with K1-group information. This semigroup, termed Cu1-semigroup, is constructed as equivalence classes pairs consisting positive element in stabilization given C?-algebra unitary unitization hereditary subalgebra generated by element. show Cu1-semigroup well-defined continuous fu...
Using a magnetic Frederiks transition technique, we measure the temperature and concentration dependences of splay K1, twist K2, and bend K3 elastic constants for the lyotropic chromonic liquid crystal sunset yellow formed through noncovalent reversible aggregation of organic molecules in water. K1 and K3 are comparable to each other and are an order of magnitude higher than K2. At higher conce...
